The Rochester Rhinos became the first visiting team to lose at Highmark Stadium in Pittsburgh this season, dropping a 2-0 decision to the Riverhounds on Friday.

Pittsburgh, last in the standings entering the match, was 0-6-2 at home before scoring a pair of second-half goals.

But they were coming off a 2-1 victory on July 2 and had already defeated the Rhinos (6-6-6, 24 points) this season, 3-2, on June 7 at Sahlen's Stadium.

Andrew Marshall headed in a free kick in the 51st minute and Alfonso Motagalvan doubled the lead in the 66th minute off a corner kick to lift Pittsburgh (3-9-5, 14).

The Rhinos have now scored just two goals in their last five USL Pro matches.

Jonny Mendoza appeared to give Rochester a 1-0 lead in the 16th minute but was called offsides before his shot found the net.

The Rhinos possessed for much of the first half and had the better of the few scoring chances.

Babacar Diallo found himself behind the defense and onsides on a corner kick, but his header was high and right.

The Riverhounds were the sharper team in the second half and got on the board on Marshall's goal.

A hand ball set up a free kick just outside the box on the right and Marshall was able to head it in just before Rhinos goalie John McCarthy could get to it.

Motagalvan, who played for the Rhinos in 2010 and 2011 under coach Bob Lilley, was credited with the second goal after a corner kick was deflected and grazed off his ankle to the lower right corner of the goal.

Flash in action

The Western New York Flash (6-8-2, 20 points) travel to BBVA Compass Stadium to take on the Houston Dash (4-9-1, 13) at 9 p.m. Saturday.

The Flash lost each of the first two matchups with the Dash and are coming off a 2-1 loss at Seattle on Wednesday.
